+The following is a list of files and features that are going to be
+removed from the U-Boot source tree.  Every entry should contain what
+exactly is going away, when it will be gone, why it is being removed,
+and who is going to be doing the work.  When the feature is removed
+from U-Boot, its corresponding entry should also be removed from this
+file.

+---------------------------
+
+What:  "autoscr" command
+When:  August 2009
+Why:   "autosrc" is an ugly and completely non-standard name.  The "autoscr"
+       command is deprecated and will be replaced the "source" command as
+       used by other shells such as bash.  Both commands will be supported
+       for a transition period of 6 months after which "autoscr" will be
+       removed.

+
+What:  Individual I2C commands
+When:  April 2009
+Why:   Per the U-Boot README, individual I2C commands such as "imd", "imm",
+       "imw", etc are deprecated.  The single "i2c" command which is
+       currently enabled via CONFIG_I2C_CMD_TREE contains the same
+       functionality as the individual I2C commands.  The individual
+       I2C commands should be removed as well as any references to
+       CONFIG_I2C_CMD_TREE.

+
+What:  Legacy NAND code
+When:  April 2009
+Why:   Legacy NAND code is deprecated.  Similar functionality exists in
+       more recent NAND code ported from the Linux kernel.
